What is in OxyELITE Pro and How Does it Work?

One of the most incredible things about OxyELITE Pro is that it only contains six active ingredients. This is USP Labs’ style – they find and target the exact ingredients needed to get the job done, and toss out the rest.

No more guesswork, no more weak “kitchen sink formulas”, and no more unwanted side-effects from ingredients that “might” work. Just thermogenic heat, energy, focus, and fat burn. Let’s take a look at each one.

A Primer on T3 and T4 Levels in the Thyroid

Before we begin, you need to understand a little bit about how your thyroid functions. This is because OxyELITE Pro uses natural extracts that activate certain thyroid functions, and the USPLabs literature doesn’t really explain what is going on. So we’re here to save you.

There are two very important thyroid hormones, thyroxine (T4) and triiodothyronine (T3). They are tyrosine-based hormones that your thyroid gland produces whose prime responsibilities are to regulate your metabolism. The ratio of T4 to T3 released by the thyroid into your bloodstream is about 20 to 1.

However, T3 is 3-4 times more potent than T4! T4 is converted to the active T3 within cells by a process called deiodinases.

All about T3 – What it Does and Why it’s Great

Additionally, T3 increases the rate of protein synthesis via the production of RNA Polymerase I and II, which is an enzyme that produces RNA chains.

Meanwhile, T3 increases your glycogen breakdown and glucose synthesis rates during gluconeogenesis. It also decreases the effects of insulin, which normally leads to fat storage.

T3 also stimulates cholesterol breakdown and increases the number of LDL receptors – which means you’ll break down more triglycerides with higher T3.

Finally, T3 may increase serotonin in the brain, which would put you in a better mood. This has only been truly proven in animal studies though.

Enough about T3! How Do I Get Some of this Stuff?

Now, there are prescription drugs available to synthetically boost T3 levels, but those are for people with major thyroid disorders. 99%+ of us don’t need or want to mess with these dangerous synthetics. In fact, if you are taking a thyroid medication, you should not be messing with OxyELITE Pro and need to talk to your doctor.

But we would like to give our bodies a slight natural kick into converting T4 into T3. This is where OxyELITE Pro comes in.

On to the OxyELITE Pro Ingredients…

Bauhinia purpurea is a type of flowering plant that comes from South China and is known to grow in Hawaii, California, Texas, and Florida.

Studies show that Bauhinia purpurea extract increased T4 by 37% while increasing T3 by 83% in healthy adult animals. An incredible adjustment to the T3 to T4 ratio![1]

Even crazier, another study showed that after you give animals drugs that severely diminish their T3 and T4 levels, Bauhinia purpurea was able to counteract this and completely restore their thyroid hormone levels![2] We would never want to do this to ourselves, but it shows how powerful Bauhinia purpurea is.

Bacopa monnieri (Leaf)

Bacopa Monnieri (or Water Hyssop) is a type of perennial. This plant may be even more exciting than Bauhinia purpurea because studies show that its extract allows your body to naturally increase T4 levels by approximately 41% compared to controls [3]

So what USPLabs has done here is added an extract that increases T4 (Bacopa Monnieri), and then combined it with an extract that will convert more to T3 (Bauhinia purpurea), giving you a winning combination and massive fat-burning potential!

This combination is what makes OxyELITE Pro so much better than the rest – You are getting a double-whammy of energy expenditure. When you take that first capsule of OxyELITE Pro and start getting hot, this is a main reason why.

But we’re not done yet!

A Primer on the Alpha-2 Adrenergic Receptor

Sorry folks, but we have to quickly go back to the text books.

Adrenergic receptors in your cells sense specific molecules outside of the cell and use them to activate various responses. The Alpha-2 Adrenergic Receptor is a very important one that is targeted mainly by noradrenaline (norepinephrine) and adrenaline (epinephrine).

When you are under great deals of stress or are working extremely hard, your body releases adrenaline in the form of norepinephrine and epinephrine. Your alpha-2 receptors are then activated by the norepinephrine and/or epinephrine, which causes various types of “fight-or-flight” responses. For instance, the heart rate will increase, your pupils will dilate, energy will be mobilized, and blood flow diverted from other non-essential organs to skeletal muscle.

While that sounds exciting, the Alpha-2 receptor’s fight-or-flight response also does something else – it inhibits lipid breakdown within bodyfat, meaning it tells your body to save its fat![4] This makes sense, as it’s trying to save your life and put you into “survival mode”, but nowadays, we’d like to diminish that part of the Alpha-2 receptor’s job. Especially since we’re talking about adipose fat tissue, or bodyfat found in your gut, lovehandles, and other trouble spots.

How can we get these Alpha-2 receptors to chill out and stop limiting lipolysis? Enter OxyELITE Pro:

Yohimbe (also known as Johimbe) is a family of plants related to the evergreen tree. Many plants in this family have an active compound named Rauwolscine HCl, which is also known as α-yohimbine and corynanthidine.

You’ve probably heard of yohimbine or yohimbine HCl, which is in many fat-burners. Yohimbine is able to stop alpha-2 receptors, which is what we want, but it also stops alpha-1 receptors – which slows lipolysis and thus negates everything we were doing with the alpha-2 receptors. This makes yohimbine ineffective in every study, and may also bring side effects.[5]

Rauwolscine/α-yohimbine, however, has a slightly different structure as yohimbine. This structure makes it act as an alpha-2 receptor blocker, yet doesn’t mess with alpha-1 as its different structure does not activate alpha-1.[6]

Thus, USPLabs in their genius ways have found a great solution to the yohimbine problem! We can now block alpha-2 receptors without screwing everything else up!

In fact, Rauwolscine blocks your alpha-2 receptors just as much as yohimbine, but is 50 times less effective on alpha 1-adrenoceptors![5] This is one of the holy grail pathways of fat-burning! So ditch that Yohimbine and check out Rauwolscine in OxyELITE Pro!

Cirsium Oligophyllum (Whole Plant Extract)

Cirsium Oligophyllum is another perennial plant found in East Asia. It has no known hazards, but this incredible extract simply reduced gains in bodyweight by 6.6%, subcutaneous fat mass by 26.2%, yet visceral fat mass by only 3%![7]

This is incredible because it’s subcutaneous fat that is just below the skin! Visceral fat, however, is the “organ fat” that your body needs a fair amount of, although obese individuals have far too much of this as well.

Greatest of all, cirsium oligophyllum extract works incredibly synergistically with caffeine[7], which of course is also in OxyELITE Pro! When mixing it with the alpha-2 receptor antagonists and caffeine in OxyELITE Pro, fat-burning is far exceeded than when using cirsium oligophyllum extract all alone!

In fact, the potency of caffeine combined with Cirsium Oligophyllum was nearly 10 times greater than Cirsium Oligophyllum alone.

Caffeine

You should already know that caffeine is a safe way to increase energy expenditure and heat you up. This leads to increased fat breakdown via lipolysis and lipid oxidation. That’s why it’s in every single stimulant-based fat-burner and we’re not even going to bother linking to studies about it.

Even better, caffeine also makes you alert, focus better, and gives a euphoric feeling.

And as we mentioned above, caffeine is synergistic with cirsium oligophyllum, making “the whole greater than the sum of the parts” in OxyELITE Pro.

Caffeine is a no-brainer here, but the important thing to note is that OxyELITE Pro only contains 100mg caffeine per capsule. Unlike other thermogenic fat-burners, this product does not rely on ridiculous amounts of caffeine to get you hot and wired and then give you a nasty crash. Instead, it is merely a synergistic agent with the rest of the ingredients, along with a nice, safe dose to get your metabolism moving.

1,3-Dimethylamylamine HCl

1,3–Dimethylamylamine HCl is also known as DMAA or Methylhexaneamine. It was originally discovered from the oil of geranium plant stems, which have been used as a food additive for centuries.

If you’ve ever used Jack3d, you know what 1,3 is all about. This stuff is amazing. 1,3 Dimethylamylamine HCl is a long-lasting, mild stimulant that increases energy and alertness, and puts you in “the zone” with incredible amounts of focus and concentration.

Like the other ingredients in OxyELITE Pro, it is synergistic with caffeine. The quick caffeine high (and subsequent crash) is limited by the longer-lasting germanium extract. Also note that with only 100mg of caffeine per capsule, you won’t get a bad crash from OxyELITE Pro like other fat-burners bring.

1, 3 Dimethylamylamine HCl is safe in small doses, but never exceed recommended dosage and follow directions. Note that some organizations, such as WADA, test for this compound and ban it, so check your drug testing sponsor if you are getting tested.

If you’ve never taken Jack3d, you will LOVE OxyELITE Pro for this stuff alone – let alone the rest of the incredible ingredients inside!
